VAIP CEKENTING AND SHIPPING- Patented Feb. 11,1908.

To all whom it may concern:

Be it known that I, HARRY I. ILLINGWORTH a citizen of the United States, and resident Swampscott, in the county of Essex and State of Massachusetts, have invented an Improvement in Vam Cementing and Snipping Machines, ofwlnch the following description, in connection with the accompanying drawings, is a specification, like letters on the drawin s representing like parts.

nmaking certain kinds of shoes, the uppers at their inside edges are cemented and turned over so as to make a smooth turned edge, and as the throat. of the vamp is curved, it is necessary to snip the edge, in order that it may be smoothly turned over. The snipping and cementing have hitherto been. accomplished separately and laboriously, at considerable expense and delay.

My invention aims to accomplish the snipping and cementing simultaneously, and to this end I provide a machine having means for delivering the narrow line of cement around "the edge of the vamp exactly as wanted, and snipping means under the control of the operator for snipping such limited portion of the edge as the skill of the opera tor and the requirements of the work may demand. The 'constructional details and further advantages and operation of my invention will be pointed out in the course of the following description, taken with reference to the accompanying drawings, in which I have shown one embodiment of my invention.

In the drawings Figure 1 is a side view of themachine, parts being broken away for clearness of illustration; Fig. 2 is a perspective view of an enlarged detail of .the cementing and snipping wheel; Fig. 3 shows the machine in front elevation; Fig. 4 is, a plan view of a vamp after the same has been run through my machine; Fig. 5 is a side elevation taken on the line 5-5, Fig. 1,

showing the sni ping and cementing wheel, the upper "part being sectioned to show the arrangement and relation of the snipping knives, and the lower part being sectioned wheel; Fig. 6 is a vertical cross-sectional view of the under feed-wheel; Fig. 7 is a side elevation of said feed-wheel looking at the right hand side thereof Fig. 6; Fig. 8 is a front elevation of the cam device for operating the snipping knives; and Fig. 9 is a cross-sectional view showing the relation of said cam to the ocmenting and sni ping wheel.

From a suitab e basel extends a standard 2 provided with an overhanging arm 3 1n whose op osite ends 4, 5 is jomnaled a shaft 6 driven by a belt pulley 7 and carrying acemen'ting and sni ping wheel 8 at its outer front end secured fixedly thereto by any suitable means, as by a nut 9. Above the wheel 8 is a cement tank 10 having a cement delivering nozzle 11.-

It will be understood that although describing in.detail the specific embodiment of my invention herein shown, I do not restrict myself thereto, as I intend this case to cover my invention broadly, as I regard it as new to provide means broadly considered for cementing and snipping a vamp as it is fed through the machine, irrespective kind of snipping arrangement or of cementing arrangement, it being essential merely, in the broadest. aspect of my invention, thatas the vamp or other article is fed forward it shall be properly cemented and properly cut at the specific place or places required.

With the above understanding, again referring to the constructional details, I have provided feeding mechanism in the form of a positively driven roll 12 located vertically below the wheel 8 and held fast on a shaft 13 i by a nut 14 so as to positively feed the vamp 15' when placed between the feeding members 12 and 8 being guided in accurate position by an edge guide or rest 16 adjustably secured to the bearing 4 at 17. For some kinds of work, and with'some workmen, it is desirable to omit the workrest. To accommodate the machine to different thicknesses of stock, the journaled bearing 18 of the feed shaft 13 is pivotally supported at 19 on a post 20 yieldingly supported on a spring 21 to slide in a fixed vertical bearing 22 on the base 1. At its opposite end the shaft 13 is pivoted at 23 in the standard 2 and is positively driven by intermeshing gears 24, 25.

The wheel 8 is of peculiar formation, being provided with two series of peripheral cement-carrying pockets, extremely narrow and inclosed by walls so as to prevent the cement from running or stringing, and cause it to deliver on the leather in the restricted narrow line or band desired. While this construction, and in fact all other details of of the my invention may be made in various ways grooves 26, 27 in the wheel, thereby leaving 'three ribs 28, 29, 30, and at suitable intervals I mill transverse grooves across the shallow ooves 26 and 27 and drive into these shalow grooves thin'pieces of steel which constitute transverse walls 31 terminati however, in the middle rib 29, thereby dividing the cove 26 into [a series of entirely boun ed po'ckets. On the opposite side of the 'wheel I provide a series 0 radial slits 32 preferably in line with the dividing walls 31, and in these slits I mount a corresponding series of snipping-knives 33, as clearly shown in Figs. 2, 5 and 9, each knife being provided with aprojecting ear or .-lug 34arranged to travel in acam-path 35 of the path cam 36, said lugs 34 and path 35 being so positioned that normall the ends of the knives pro'ect just flush witlithe ribs 29, 30, thereby divi 'ng the shallow lglroove 27 into a series of pockets similar to t mounted on'the shaft 6 and remains nor- I mally in a stationary position, being actuated tion by a spring 44, see Fig. 3. The cam 36 has an offset in its path which is normally turned to the rear, as shown in Figs. 3 and 8, so that thereby as the snipping knives come found, they simply go out and in as shown in Fi 3, without accomplishing any work, there y leaving only the cementln action in o eratlon. But by depressing t e treadle t e offset 45 in the cam-path 35 is turned into a vertical position directly over the feed wheel, thereby hung the snipping action into' operation. For t 's purpose the feed wheel is provided with a series of radial slits 46 corresponding in number and alinement to the snipping knives, said slits having concave bottoms, as shown clearl in Fig. 6, so that they are self-clearing. T us, whenever the snipping knives are brought into cooperative action with the feed wheel for snipping, said knives enter the slits 46 and neatly and quickly cut the leather as desired.

The cementing wheel 8 enters the cement delivery opening 11 and is prevented from receiving more than the desired thin layer of cement in its pockets by lateral scrapers or (pads 47 at the sides held by clamps 48,

transverse scrapers or pads 49 held by clamps 50 at the front and back of the openmg 11, all so arranged that they may be tightened in adjustment as required, the scrapers 47 beingadjusted simply by tightening the clamps 48, and thescrapers 49 being i e ad'acent series of pockets at the other side of t e wheel, see Fig. 2, and the upper part of Fig. 9. The cam 36, is loosely the edge of t e vamp which is to be folded over. As the vamp. is fed forward, the cement is deposited along the line 53, as

shown in 4,. and when the cementmg wheel approaches thecurve 54, the operator depresses the treadle rod 43,. thereby shifting the cam 36 downward, so that the offset 45 causes the snipping knives instantly to cooperate the slits 46 in .the feed roll 12, thereby be to snip the edge of the upper, said snipping being continued until the curved portion of the edge has been cemented and snipped, whereupon the treadle rod 43. is released, thereby instantly shifting the position of the cam andsto ping the smp ing action, but without inter ering in the s ightest with the continuance of the cementing to the end at 55, Fig. 4. It will be understood that in Fig. 1 I have merely indicated a fragmentary portion of the vamp in place in the machine, for the purpose of rendering clear the operation of the machine. If a thicker vamp, or other iece of material is to be cemented, it read y goes between the feed roll and the cement wheel by reason of the yielding arrangement, which permits them to se arate..v In this form of my invention I pre er to'have the snipping knives in the cement wheel to cut against-or into the feed roll, rather than to have the arrangement reversed, as thereby the knives help to 7 form the retaining pockets and also the a jEaratus, as constructed, tends to clean itself.

ikewise the constant motion of the snipping knives is desirable to prevent their getting stuck or rendered inefiective because of the sticky, smeary nature of the cement used.

I have shown my invention as constructed for applying the thin, viscous, volatile cement, composed of rubber and the like dissolved in naphtha, and it will be understood that the machine will be modified and changed to suit other cements as required, without departing from the main general features of my invention.

In a co-pending application, Serial No. 348,678 I have shown and claimed another species of my generic invention.
